Any others?
How do some of these compare? Polar alignment ability is an important feature.

Hi Greg, just a quick observation on the polar alignment requirement. It is really going to depend on what focal length(s) you want to settle on. In my case I’m sticking to my Samyang 14mm f2.8 lens with the Canon 60Da resulting in a very wide field. Obviously this is a lot more forgiving on polar alignment accuracy than trying to image with a 200mm lens. I find that with the 14mm lens on board I achieve a satisfactory polar alignment by using a digital inclinometer to set the altitude and then a magnetic compass to align with true south. My mount is the Skywatcher Star Adventurer and the tracking is sufficiently accurate in this configuration to produce acceptable subs. I may apply a light touch of BlurXterminator in Pixinsight in post processing to tidy up the stars a little.
